As the embodiment shown in FIG. 2, the display module 10 includes adisplay panel 100, a backlight module 300, and a sensing antenna 500.The display panel 100 preferably includes a first substrate 110, asecond substrate 120, and a display medium layer 130 disposed betweenthe first substrate 110 and the second substrate 120. The firstsubstrate 110 preferably has a pixel electrode layer or other controlcircuit module for controlling the display medium layer 130. The outersurface of the second substrate forms a display surface 101 (as shown inFIG. 3B). A color filter layer (not shown) is preferably formed on thesecond substrate 120, but not limited thereto. In other embodiments, thecolor filter layer can be disposed between the display medium layer 130and the first substrate 110, which can be referred to “array on colorfilter” or “color filter on array”. In the embodiment, the display panel100 is preferably a liquid crystal panel; hence the display medium layer130 is a liquid crystal layer, wherein the electrical field that drivesthe liquid crystal layer can be horizontal electrical field and/orvertical electrical field. In different embodiments, however, thedisplay medium layer 130 could be an electro-phoretic display layer, anelectro-wetting display layer, or other non-self-luminous medium layers.The backlight module 300 has a light exit surface 301 and a reflectiveplate 310 disposed opposite to the light exit surface 301, wherein thedisplay panel 100 is stacked on the light exit surface 301 in a contactor non-contact manner for receiving the backlight emitted from the lightexit surface 301. The backlight module 300 could be a direct lightdesign or a side-lit design. In this embodiment, the backlight moduletakes the side-lit design and includes an optical film 320, a lightguide plate 330, a light source 340, and the reflective plate 310. Theoptical film 320 is stacked on the light guide plate 330 and is selectedfrom a polarizing film, a brightness enhancement film, a diffusing film,or other suitable optical films, or a combination of at least two of theabove films. The light source 340 is disposed at the side of the lightguide plate 330, wherein the reflective plate 310 is disposed on thebottom surface (not shown) of the light guide plate 330, and the sideconnects the light exit surface 301 and the bottom surface. The lightgenerated by the light source 340 enters the light guide plate 330 fromthe side surface, exits from the top surface of the light guide plate330 after being reflected, and exits the light exit surface 301 afterpassing through the optical film 320. In other words, in thisembodiment, the light exit surface 301 is formed on the outer surface ofthe optical film 320 closest to the display panel 100. Besides, aportion of light exited from the bottom surface of the light guide plate330 can be reflected back into the light guide plate 330 by thereflective plate 310.

As shown in FIGS. 2, 3A, and 3B, the sensing antenna 500 includes a body510 and two signal connecting terminals 530 connecting the body 510. Thesensing antenna 500 is preferably a loop coil and can be formed on aflexible circuit board or a printed circuit board. The sensing antenna500 also can be directly formed on a desired substrate or plate bydifferent processes. The sensing antenna 500 in this embodiment isdisposed on a surface of the reflective plate 310 that faces away fromthe light exit surface 301, i.e. a surface of the reflective plate 310opposite to the light guide plate 330. In other words, the reflectiveplate 310 has a first surface (or namely top surface) and a secondsurface (or namely bottom surface) is opposite to the first surface,wherein first surface of the reflective plate 30 faces and closest tothe light guide plate 330 and second surface of the reflective plate 30not faces to and far away the light guide plate 330. The reflectiveplate 310 is made of a polymer material substrate coated with othercolor paint or a polymer single/multi-layer for refracting/reflectinglight. The polymer material includes Poly(Methyl methacrylate) (PMMA),Polycarbonate (PC), (Methyl methacrylate)Styrene (MS), Poly(EthyleneTerephthalate) (PET), Poly(Ethylene Naphthalate) (PEN), PolyStyrene(PS), Polypropylene (PP), or other suitable materials or a combinationthereof, or a copolymer thereof, wherein the properties of the abovematerial can be found in the MSDS (material safety data sheet). Forexample, preferably, the polymer single/multi-layer forrefracting/reflecting could be a single layer of Poly(EthyleneTerephthalate) or a multiple layer of Polypropylene and Poly(EthyleneTerephthalate). The reflective plate does not include metal film oralloy film, so that the reflective plate 310 will not shield the sensingelectromagnetic wave (i.e. magnetic field line) of the sensing antenna500. When a sensing device approaches the display surface 101 andundergoes sensing to transfer or receive data, it can be regarded as thesensing antenna 500 passing through the display module 100 and leavingthe display surface 101. In this embodiment, since no housing (or namelyrear shell, or namely outer shell) is disposed on the outer side of thereflective plate 310, the sensing antenna 500 is not shielded by thebacklight module 300 when viewing from the back surface of the backlightmodule 300 (as shown in FIG. 3A), wherein at least a portion of theouter surface of the sensing antenna 500 is exposed outside thebacklight module 300. That is, the sensing antenna 500 can be seen fromthe back side of the display module before it is assembled with otherunits of the electronic device. The inner surface of the sensing antenna500 is a surface of the sensing antenna 500 that contacts the reflectiveplate 310, i.e. inner surface of the sensing antenna 500 contacts thebottom surface of the reflective plate 310. The outer surface of thesensing antenna 500 is a surface of the sensing antenna 500 that doesnot contact the reflective plate 310, i.e. outer surface of the sensingantenna 500 not contact bottom and top surfaces of the reflective plate310. Wherein inner surface of the sensing antenna 500 opposites to outersurface of the sensing antenna 500. As the side view shown in FIG. 3B,the sensing antenna 500 preferably protrudes from the surface of thereflective plate 310 (such as bottom surface of the reflective plate310), and more preferably protrudes from the bottom surface of the wholebacklight module 300. Moreover, for the convenience of signal connectionof the signal connecting terminal of the sensing antenna with the systemterminal after assembly, in the preferred embodiment, the signalconnecting terminals 530 of the sensing antenna 500 are disposed on asurface of the sensing antenna 500 that faces outward or is exposed.

For an active sensing antenna 500, the above design decreases the metalshielding of the sensing antenna 500 on the back side. Hence there isless interference to the radio frequency field generated by the sensingantenna 500. For a passive sensing antenna 500, this kind of design alsoreduces the probability of being interfered with the radio frequencyfield emitted by an external communication apparatus. In otherembodiments, the outer surface of the sensing antenna 500 is shielded bya shielding device, i.e. a shielding device is disposed under thesensing antenna 500 and the sensing antenna 500 is disposed between thereflective plate and the shielding device; it can be regarded as thesensing antenna 500 passing through the display module 100 and leavingthe display surface 101 when a sensing device approaches the displaysurface 101 and undergoes sensing to transfer or receive data. At thistime, the strength of the sensing magnetic field line leaving thedisplay surface is larger than the strength of the sensing magneticfield line living the shielding device (e.g. the rear shell). Though thesensing magnetic field lines exit both over and under the sensingantenna 500, for the sensing magnetic field line over the sensingantenna 500, the sensing magnetic field line under the sensing antenna500 destructively interferes and weakens the sensing magnetic field lineover the sensing antenna 500 no matter whether the sensing magneticfield line under the sensing antenna 500 is reflected by other units ornot. Therefore, the sensing magnetic field lines over and under thesensing antenna 500 should be considered separately, it is not insteadof being treated interchangeably or equally. The material of theshielding device (or namely shielding unit) includes reflectivematerial, i.e. light tight conductive material, such as metal or metalalloy. The shielding device includes a back shell (as shown in FIG. 5C,could be an outer shell or a rear shell of an electronic device), abattery, a rigid printed circuit board, or other units, or a combinationof at least two of the above. The back shell is preferably the outmostshell (or referred as the outmost casing) without any other shell orframe; thus the battery and the rigid printed circuit board or otherunits are disposed under the sensing antenna 500 and between the backshell 400 and the sensing antenna 500. The sensing antenna 500 isdisposed between the display module 100 and the shielding unit.

In the preferred embodiment, a portion of the display module 100 isbetween the display surface 101 and the body 510 of the sensing antenna500 (as the region labeled by the dotted line shown in FIG. 4A), so thata portion of the display panel overlaps the sensing antenna and has anoverlapping area of a projection on a plane, wherein a metal projectioncoverage rate (metal projection coverage percentage) of the metal layerin the overlapping area is not more than about 90%, preferably lowerthan about 70%. The metal projection coverage rate (Ac) preferablyrefers to, when a display panel of the display module 100 having adisplay surface with a metal layer is projecting on a virtual plane, theratio of the projection area A2 of the metal layer in the overlappingarea on the virtual plane to the projection area A1 of the sensingantenna 500 on the virtual plane in percentage (%), i.e.Ac=(A2/A1)×100%. The display surface includes a display area and aperipheral circuit area, e.g. the surface of the display panel faces theuser. In other words, the display panel has the display area and theperipheral circuit area. The metal layer preferably refers to a signaltransfer device/line (wire) in the display module made of reflectivematerial, i.e. non-transparent conductive material, e.g. made of metalor metal alloy material. In general, the signal transfer device/line(wire) at least includes scanning line, data line, capacitor line,connecting wire, contact pad, transistor, or other devices or lines(e.g. power wire, reference potential wire, reflective electrode,repairing wire, capacitor electrode, or other devices or wires). Inother words, the numerator of the metal projection coverage rate (Ac)refers to the projection area (A2) of the metal layer (i.e. signaltransfer device/wire) in the overlapping area of the display module 100on the virtual plane, wherein the overlapping area refers to the regionof the display module 100 that overlaps the body 510. The projectionarea (A2x) of the transparent conductive or non-conductive material inthe overlapping area of the display module 100 on the virtual planealong with the other projection area (Ax, as shown in FIG. 4B) of thedisplay module 100 that is not in the overlapping area or does notoverlap the body 510 are ignored. The denominator of Ac refers to thearea (A1) of the sensing antenna projecting on the virtual plane. Inthis embodiment, As shown in FIG. 4B, taking a perspective view likeX-ray or other approach at the display module 100 from the normaldirection of the display surface 101, the ratio of the projection areaof the metal layer in the projecting region (as shown by the dottedline) of the sensing antenna 500 to the projection area of theprojecting region of the sensing antenna 500 in percentage (%) isdefined as the metal projection coverage rate. Inside the display area103, the display panel 100 includes pixel electrode layer, liquidcrystal layer, color filter layer, etc. In the peripheral circuit area105, the display panel 100 includes one or more layers of signaltransfer wire. After the projection observation, the projection area ofthe metal area (layer) of the overlapping portion of each layer will notbe calculated repetitiously. In this embodiment, taking a sensingantenna 500 overlapping a portion of the display area 103 and a portionof peripheral circuit area 105 as an example, the numerator of the metalprojection coverage rate (Ac) equals the projection area (A21) of themetal layer (i.e. signal transfer device/wire) in a portion of thedisplay area 103 that overlaps the body 510 and projects on the virtualplane pluses the projection area (A22) of the metal layer (i.e. signaltransfer device/wire) in a portion of the peripheral circuit area 105that overlaps the body 510 and projects on the virtual plane. Theprojection area (A2x) of the transparent conductive or non-conductivematerial in the display module 100 and the peripheral circuit area 105that overlaps the body 510 and projects on the virtual plane along withthe other projection area (Ax, as shown in FIG. 4B) of the displaymodule 100 not overlapping the body 510 are ignored. The denominator ofAc refers to the area (A1) of the sensing antenna projecting on thevirtual plane. That is Ac=(A2/A1)×100%, wherein A2=A21+A22. In otherembodiments, the sensing antenna 500 only overlaps the display area 103,the numerator of the metal projection coverage rate (Ac) is theprojection area (A21) of the metal layer (i.e. signal transferdevice/wire) in the portion of the display area 103 that overlaps thebody 510 and projects on the virtual plane, wherein the projection area(A2x) of the transparent conductive or non-conductive material in thedisplay module 100 that overlaps the body 510 and projects on thevirtual plane along with the other projection area (Ax, as shown in FIG.4B) of the display module 100 not overlapping the body 510 are ignored.The denominator of Ac refers to the area (A1) of the sensing antennaprojecting on the virtual plane. That is Ac=(A2/A1)×100%, whereinA2=A21. Alternatively, the sensing antenna 500 only overlaps theperipheral circuit area 105, the numerator of the metal projectioncoverage rate (Ac) is the projection area (A22) of the metal layer (i.e.signal transfer device/wire) in the portion of the peripheral circuitarea 105 that overlaps the body 510 and projects on the virtual plane,wherein the projection area (A2x) of the transparent conductive ornon-conductive material in the peripheral circuit area 105 that overlapsthe body 510 and projects on the virtual plane along with the otherprojection area (Ax, as shown in FIG. 4B) of the display module 100 notoverlapping the body 510 are ignored. The denominator of Ac refers thearea (A1) of the sensing antenna projecting on the virtual plane. Thatis Ac=(A2/A1)×100%, wherein A2=A22. Moreover, when the sensing antennais a loop coil, its projection area refers to the total area of the loopcoil and the area surrounded by the loop coil. As the test data shown inFIG. 4C, when the metal projection coverage rate of the correspondingarea between the sensing antenna 500 and the display surface 101 is lessthan about 90%, it is able to sense the sensing antenna 500 andundergoes transferring data or energy at the position about 0.1 cm awayfrom the display surface. When the metal projection coverage rate of thecorresponding area between the sensing antenna 500 and the displaysurface 101 is less than about 70%, it is able to sense the sensingantenna 500 and undergoes transferring data or energy at the positionabout 1 cm away from the display surface. It is declared that the metalprojection coverage rate mentioned in this embodiment could be used inthe following embodiments.

FIG. 5A shows a modified embodiment of the embodiment shown in FIG. 2.In this embodiment, the display module 100 further includes a rear shell400 covers the surface of the reflective plate 310 that faces away fromthe light exit surface 301. The rear shell 400 preferably refers to anoutmost housing of the display module 100 or a metal part whichincreases the strength of the display module 100. In a differentembodiment, however, the rear shell 400 could be made of other material.In this embodiment, an opening 303 is preferably formed in the rearshell 400 at a position of the rear shell 400 that corresponds to thesensing antenna 500 to at least partially expose the surface of thesensing antenna. Preferably, the opening 303 totally exposes the surfaceof the sensing antenna 500. In other words, when viewing from the rearshell 400, at least a portion of the surface of the sensing antenna 500could be seen through the opening 303. Accordingly, though the sensingantenna 500 does not protrude out of the rear shell 400, the signalreceiving or transmitting of the sensing antenna 500 is not influenced.In different embodiments, the sensing antenna 500 can protrude out ofthe rear shell via the opening 303 to facilitate signal connection ofthe signal connecting terminal 530 with the system terminal afterassembly. In this embodiment, the sensing antenna 500 can be disposedbetween the shielding device (unit) and the reflective plate 310. Fornot influencing the signal receiving or transmitting of the sensingantenna 500, in addition to the rear shell having an opening, othershielding units, e.g. battery and/or rigid printed circuit board, willnot overlap the sensing antenna 500. Therefore, besides the sensingelectromagnetic radiation (or called sensing magnetic field line) of thesensing antenna 500 is able to pass through the display module 100 andleave the display surface 101 when the sensing device approaches thedisplay surface 101 and undergoes sensing to transfer or receive data,the sensing electromagnetic radiation (or called sensing magnetic fieldline) of the sensing antenna 500 is able to pass through the rear shell400 and leave when the sensing device approaches the rear shell 400 andundergoes sensing to transfer or receive data, hence to increase thesensing strength and the user's convenience.

In different embodiments, considering the effect of the size of theopening 355 of the rear shell 400 on the sensing antenna 500, it isrequired to design the percentage of exposure of the sensing antenna 500by the opening, i.e. design in accordance with the metal projectioncoverage rate (Ac). The metal projection coverage rate (Ac) equals to(A2/A1)×100%. The numerator is the projection area (A2) of the rearshell 400 that overlaps the body 510 and projects on the virtual plane,wherein the denominator refers to the area A1 of the sensing antennaprojecting on the virtual plane. That is Ac=(A2/A1)×100%. The otherprojection area (Ax) of the rear shell 400 projecting on the virtualplane and not overlapping the body 510 is ignored. For not influencingthe signal receiving or transmitting of the sensing antenna 500, inaddition to the rear shell having an opening, other shielding devices(units), e.g. battery and/or rigid printed circuit board, do not overlapthe sensing antenna 500. In other embodiments, the rear shell 400 couldhave no opening 303, wherein the material of the rear shell is selectedfrom materials containing no metal or metal alloy, e.g. glass orpolymer. At this time, the position of the shielding unit (e.g. batteryand/or rigid printed circuit board) disposed must be taken intoconsideration with designing the percentage (%) shielded by theshielding unit of the sensing antenna 500, i.e. designing with the metalprojection coverage rate (Ac). The metal projection coverage rate (Ac)is equal to (A2/A1)×100%. The numerator is the projection area (A2) of aportion of the shielding unit that overlaps the body 510 and projects onthe virtual plane, wherein the denominator refers to the area A1 of thesensing antenna 500 projecting on the virtual plane. That isAc=(A2/A1)×100%, wherein A2=A21+A22. The other projection area (Ax) ofthe shielding unit projecting on the virtual plane and not overlappingthe body 510 is ignored. In other words, the projection area of at leastone of the battery or the rigid printed circuit board of the shieldingunit projecting on the virtual plane and overlapping the body 510 arerespectively A21 and A22. When the battery and the printed circuit boardboth overlap the body 510, A2=A21+A22. When only one of the battery andthe printed circuit board overlaps the body 510, A2=A21 or A2=A22. Themetal projection coverage rate of the above two embodiments described inthis paragraph is preferably lower than about 98%, more preferably lowerthan about 96%. As the test data shown in FIG. 5B, when the metalprojection coverage rate of the projection area on the shielding unit isless than about 98%, it is able to sense the sensing antenna 500 andundergoes transferring data or energy at the position about 0.1 cm awayfrom the display surface. When the metal projection coverage rate of theprojection area on the shielding unit is less than about 96%, it is ableto sense the sensing antenna 500 and undergoes transferring data orenergy at the position about 1 cm away from the display surface.

FIG. 5C shows another modified embodiment of the embodiment shown inFIG. 2. In this embodiment, in addition to the rear shell 400, thedisplay module 10 further includes a signal connecting circuit module700 connecting the display panel 100 and providing signal to the displaypanel 100 for displaying image. The signal connecting circuit module 700is preferably made of flexible circuit board, wherein one end connectsthe display panel 100; the other end is bent and disposed between thesensing antenna 500 and the rear shell 400. With this configuration, thesensing antenna 500 can be slightly isolated from the rear shell 400;hence the actively emitting or passively responding of radio frequencyfield or sensing magnetic field by the sensing antenna 500 is lessinfluenced by the metal component (layer) in the rear shell. Therefore,when a sensing device approaches the display surface 101 and undergoessensing to transfer or receive data, the sensing magnetic field line ofthe sensing antenna 500 is able to leave the display surface of thedisplay panel 100, hence to increase the sensing effect. For making asensing device approach closer to the rear shell and undergo sensing totransfer or receive data, the sensing magnetic field line of the sensingantenna 500 is able to leave the rear shell 400 side. Besides, in thepreferred embodiment, the signal connecting terminal 530 is able toelectrically connect the connecting wire of the signal connectingcircuit module 700 via contact, for transferring message to the systemterminal via the signal connecting circuit module 700.

As shown in FIG. 6A, a display area 103 and a peripheral circuit area105 surrounding the display area 103 can be defined or divided on thedisplay panel 100. The projection location of the sensing antenna 500 onthe display surface 101 could be only in the display area 103, only inthe peripheral circuit area 105, or in both the display area 103 and theperipheral circuit area 105. Besides, the image contents of the displaypanel could relate to the projection location of the sensing antenna 500in the display area 103. For example, it can be designed in the imagecontent of the display panel 100 to display specific content at acorresponding location 107 of the sensing antenna 500 for notifying theuser to use an external sensing device for sensing to receive ortransfer data; or a system terminal processing device connected to thesensing antenna 500 can undergo next process accordingly when the useruses the external sensing device to sense at the corresponding location107 for receiving or transmitting data. For an embodiment having largersized display panel 100, as shown in FIG. 6B, a plurality of sensingantennas 500 can be disposed on the back side to correspond a pluralityof corresponding locations 107; thus the displayed image has differentcontents at different corresponding positions for the user to select.When the user makes selection to sense at one corresponding location107, the system terminal processing device gets the selection of theuser in accordance with the response of the sensing antenna 500 forundergoing further process.

FIG. 7A shows another embodiment of the display module of the presentdisclosure. In this embodiment, the display module 10 includes a displaypanel 100, a signal connecting circuit module 700, and a sensing antenna500. The display panel 100 could be a non-self-luminous panel or aself-luminous panel. The display panel 100 preferably includes a firstsubstrate 110, a second substrate 120, and a display medium layer 130disposed between the first substrate 110 and the second substrate 120.The display medium layer 130 could be a non-self-luminous material layersuch as a liquid crystal layer, an electro-phoretic display layer, or anelectro-wetting display layer. The display medium layer 130 could be aself-luminous material layer, such as organic luminous material layer orinorganic luminous material layer. The signal connecting circuit module700 connects the display panel 100 with signal and has a plurality ofdriving signal wires 710 for transferring signals to the display panel100 to display image. The signal connecting circuit module 700 ispreferably made of flexible circuit board and electrically connects aside end of the display panel 100. In different embodiments, however,the signal connecting circuit module 700 could be made of hard printedcircuit board (or called rigid printed circuit board). Moreover, thesignal connecting circuit module 700 includes a system terminalconnector 730 electrically connecting a driving signal wire 710 at oneend away from the display panel 100 for receiving control signal from asignal source and transferring it to the display panel 100.

As shown in FIG. 7A, the sensing antenna 500 is disposed on the signalconnecting circuit module 700 and has a body 510 and a signal connectingterminal 530. The sensing antenna 500 is electrically insulated from thedriving signal wires 710 for decreasing interference to each other. Inthis embodiment, two areas can be divided on the signal connectingcircuit module 700: a driving signal circuit area 701 and a sensingantenna area 703. The driving signal wires 710 and the sensing antenna500 are respectively formed as conductive wires in the driving signalcircuit area 701 and the sensing antenna area 703. Besides, the sensingantenna 500 electrically connects the system terminal connector 730 forsharing (or namely co-using) the system terminal connector 730 with thedriving signal circuit area 701 to transfer signal. FIGS. 7B-7D showmodified embodiments of the embodiment shown in FIG. 7A.

In step 1250, a variable capacitor of thematching circuit of the sensing antenna 500 modulates the capacitanceafter receiving the signal to make a frequency or a bandwidth of thesensing antenna 500 back to an original working frequency or bandwidth,hence to reduce the effect caused by the change in capacitance of thedisplay panel. With this design, even though the sensing antenna 500 isdisposed in the display module 10, furthermore in the display panel 100,the sensing antenna 500 can operate normally with reduced interference.
